Actually, the ideal female ballet body type is not very womanly - developments such as wide hips, breasts, and any sort of curvyness are selected against. Puberty is often deliberately staved off via excessive training to avoid these developments. Hot legs? Muscular, for sure, but I dunno. To me, their bodies look a bit like those of skinny teenage boys who have done tons of leg extensions, but whatever floats your boat...
